Sorry for not responding to the questions you asked sooner have been busy with other projects and my full-time jobs. Yes the carburetor is used. As far as I know it is a true carter afb. The guy who's jeep I'm trying to figure out and get running for hot it from another guy that had it on a 304 supposedly.
Have a 1976 cj7 installed a carter afb 4 barrel carburetor and of course 4 barrel intake, now when I try to start it gasoline is shooting out of the top of the carburetor. What could be causing the issue?
